battery light on...

[joshkeller]

2006 ranger 3.0. 65,000ish miles. first time i changed the oil (6 months ago) i learned the hard way to unhook the negative battery cable to avoid spark when dropping the oil filter onto the starter. got it all back together, and the battery light was on for 5 or so start cycles and went off on its own. changed the oil again saturday and unhooked the negative cable. went smoothly, replaced filter and oil, hooked cable back up. started truck and the battery light has been on ever since. getting 14.04 v at the battery with truck on, 12.8 after its been sitting off overnight. alternator is definitely charging as the lights get dimmer after shutting off truck. have a ammeter gauge hooked up off the battery now as a precaution until i can figure out how to get the battery light off. any suggestions?

Take the bulb out.... unplug the battery.... cut the wires...

Somebody useful will chip in soon.

Check the single small wire going to the alternator. I believe your ranger has one may have come loose or is about to.

I recently installed a new alternator and I didn't plug the amp meter wire up right. Battery light was glowing red until I hooked it up right.

did you clean the pole before you put it back on and its tight, I dont have a manuel for that one but you may have damaged a resistor or diode on the printed circut in the dash

Jiggled the wires on the alternator and now the light is out. Thanks guys
